Some folks here have previously worked with our MegaDetector model for categorizing camera trap images as person/animal/vehicle/empty; we are excited to announce MegaDetector version 5.0, which provides a significant speedup (3x-4x) over MegaDetector v4, and - hopefully - increased accuracy in some of the scenarios that challenged MDv4.  

MDv5 represents a change in architecture, but more importantly, an expansion of our training data to include some of the situations that make MDv4 sad, particularly human-made objects that overlapped with animals, like bait posts and traps.  You can read a bit more about our training data here.

Looking forward to feedback from the community on where MDv5 shines, fails, or anywhere in between!
